A conveyor controller for being implemented into a conveyor system includes control circuitry and one or more network interfaces for coupling with other conveyor controllers. In one embodiment, the control circuitry configured for detecting whether another conveyor controller is connected and to determine which network interface is used in order to set the direction of the conveyor system. In another embodiment, the control circuitry is configured, to receive configuration data from a conveyor controller connected to a network interface, and to detect if another conveyor controller is and to transmit configuration message to another conveyor controller that includes additional configuration data associated with the conveyor controller. In still another embodiment, the control circuitry transmits configuration data to a replacement conveyor controller upon getting a request from the replacement conveyor controller that has been connected to a network interface.

A cartridge having a housing, an outer looped element affixed at least partially in a cavity that spans substantially all of a length of the housing. A movable inner looped element is mounted a roller and positioned inside the outer looped element. Panels are radially attached to the movable inner looped element such that each of the plurality of panels extends toward the outer looped element. Movable chambers defined by a space between the panels. A first opening that spans substantially all of a first side of the outer looped element. A second opening is disposed on the outer looped element proximate to a bottom end of the outer looped element providing access to outside the cartridge. A second movable door covers substantially all of the second opening and partially defining the outer looped element when the second movable door is in a second movable door closed position.

A motorized drive roller conveyor includes an upstream zone and a downstream zone, with each zone having a drive roller, an idler roller that is driven by the drive roller, and a sensor. The upstream zone and the downstream zone are controlled by a card, which measures a gap between a first item on the conveyor and a second item on the conveyor by beginning a counter when a trailing edge of the first item passes the sensor of the upstream zone and stopping the counter when a leading edge of the second item passes the sensor of the upstream zone to generate a counter value. If the first item is stopped in the downstream zone, the card of the upstream zone causes the drive roller of the upstream zone to advance the second item into the downstream zone for a distance derived from the counter value before stopping the transportation of the second item.

A method for state monitoring in a conveyor system, and also to a control unit, to a motorized roller, to a conveyor zone, to a conveyor section and to a conveyor system for carrying out this method. The method comprises checking for the presence of a reference operating state, determining a current of the motorized roller if the reference operating state is present, and comparing the determined current of the motorized roller with a reference value for the reference operating state.

A tray destacker includes a pair of spaced-apart carriages movable vertically relative to a frame. An indexing member is carried by each of the carriages. Each indexing member is movable between a deployed position in which the indexing members are closer to one another and a retracted position in which the indexing members are further from one another. A controller is programmed to automatically split a large stack of trays into two or more smaller stacks.
